South Carolina home permit planning notes
Wind zones, floodplain, coastal review, septic, stormwater, pools, decks, and county/city authority are important early checks.
What to verify locally
- Whether your property is inside city limits or unincorporated county territory
- Which office handles zoning approval versus building permits
- Whether trade permits must be pulled by licensed contractors
- Whether HOA, historic, coastal, floodplain, wildfire, or utility approval applies
